DL BEST BALL

DL Best Ball — DraftKings DFS optimizer

Built for every contest.

GPPCashLarge fieldSmall field

Cash games and tournaments are won differently. Every week you get DraftKings Classic and Showdown lineups built for each: high floors for head-to-heads and double-ups, and for large fields, lineups that stack the teammates who score together and steer around the players everyone else is rostering. Projections come from real usage, Vegas lines and 10,000 simulations of every game, rebuilt for the latest injuries, weather and line moves.

The optimizer

One slate, four ways to attack it.

Cash and GPP are different games. Every slate gets four builds, each optimized to a different objective:

  • Top projectedBuilt with our proprietary method, refined on thousands of data points from real slates, to surface the lineup most likely to deliver. Your cash baseline.
  • Highest ceilingBuilt for the best shot at a big score, tuned on three seasons of real slates with correlation priced in, not on inflated upside numbers.
  • Highest floorThe safest build on the board: volume-locked, low-variance pieces that keep you above the cash line when the slate breaks wrong.
  • TournamentMaximizes the odds of clearing the score that ships first place: leverage off projected ownership, dupe control, stack structures that match past large-field winners, and a floor term so the build is not riding on boom-or-bust filler.

Showdown builds key off game script (blowout, shootout or grind) with the captain chosen to fit it. Lock, fade, bump or re-project anyone and every build re-optimizes around your read.
